PLOW ATTACHM ENT.

SPECIFICATION forming part of Letters Patent No. 644,980, dated March'6, 1900. Application filed December 27, 1898. Renewed August 10, 1899. Serial No. 726,846. (No modeli) citizen of the United States, residing at Chagrin Falls, in the county of Cuyahoga and Stateof Ohio, have invented certain new and useful Improvements in Plow Attachments; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to plow attachments;

and the purposes of the same are to more positively control the direction of movement of a plow by having the plow-point line and colterline one and the same and inseparable, thereby causingthe plow to follow the colter-cut line and avoid the necessity of crashing off an entire new land side; to make the entire land-side cut clearto the bottom of thefurrow and leave no hard earth below the colter for after treatment by the plow at a great loss of power and only requiring the actual turning over of the earth without resistance, due ordinarily to an unfinished preliminary cut; to have the weight and friction of the earth bear upon the" plow-point, colter, and share in such manner as to tend to hold it down in the ground irrespective of obstructions that may be encountered and which usually throw up the beam; to thoroughly turn under and cover all growths to a sufficient depth to prevent engagement with and dragging outby a harrow, and thereby obtain the full effect of their fertilizing influence, and to have the parts fixed in their adjustment and position relatively to each other, so as to maintain a continuity of the desired operation thereof in an invariable manner.

The invention consists of the construction and arrangement of parts hereinafter described and claimed.

In the accompanying drawings, Figure l is a perspective view of a plow embodying the invention. Fig. 2 is a side elevation of a part of the plow looking toward the face of the moldboard. Fig. 3 is a front end elevation of the device shown by Fig. 2. Fig. 4 is a side elevation of the plow proper looking toward the land side. Fig. 5 is a sectional top plan View of a part of the combined plow point and colter.

Referring to the drawings, wherein similar numerals are utilized to indicate correspond ing parts in the several views, the numeral 1 designates a plow proper, having, as usual, a moldboard 2 and a landside 3 and secured to a beam 4.

To the lower front portion of the moldboard 2 and forwardly continuing also the landside 3 is ashare 5, having an integral colter 6 standing upwardly in a plane at a right angle to said point and having its outer surface flush with said landside and its face adjacent the moldboard running regularly to a suitably-located point 7 on said share. The moldboard and landside are both recessed or jogged to receive the rear edges of the share and its colter member, and from the front reduced edge 8 of the share to the rear edge of the latter a gradual thickening or upper beveling exists, and the point 7 projects downwardly and forwardly in the same plane. The front part 9 of the colter 6 is also reduced to provide a cutting edge and is beveled or inclined rearwardly, being straight I at the lower portion and curved at the upper portion. The outer vertical face of the colter or that immediately over the share is beveled from the cutting edge toward the rear, and consequently gradually thickened, and the landside-face is straight. Adj ustably secured to the face of the colter above the share is a seamcr 10, arranged at an angle of inclination with, the highest part at the rear. This-seamer comprises a securing-plate 11, having an upper right-angular curved blade 12. The blade 12 has a front cutting edge to split the turning furrow, and its curve and position are such as to carry its part of furrow up and against the face sides of colter and fender, thereby forcing clogging matter up the fender. The plate 11 is held on the colter by removable bolts 14, and in said colter other holes 15 are formed to permit an adjustment of the seamer in a'vertical plane to make the grading finer and give the seamer more range.

The topportion 16 of the colter 0 on the land side is formed with a recess or rab'bet 1 7 to receive the lower end of a fender 18. This fender is gradually arched and extended rearwardly in an oblique plane and converges to a blunt point 19. The upper curved part of the front edge of the colter merges into and becomes substantially continuous with the front edge of the fender, so as to avoid formation at any point of catching shoulders or breaks. The free end of the fender projects downwardly over the moldboard, and the function of the same is to draw down and turninwardlyanysurfacegrowths. Thecurve of the fender is such that the growths will be brought over with the earth and thoroughly turned under and embedded to such a depth by the moldboard as not to be reached by the teeth of a harrow afterward used, and thereby the full fertilizing effects of such growths are obtained.

In operation the share 5 and point 7 out out the bottom of the furrow, and simultaneously the colter 6 cleanly cuts the land side of the furrow completely to the bottom of the latter, so that the plow proper meets with no resistance and has no work to do other than throw over the earth. The position and shape of the share, colter, and point is such that the weight and friction of the earth thereon at all times hold the entire plow down properly in the furrow and a regularity in the depth of cut is sustained. The earth coming in toward the plow proper over the share is split up or divided by the seamer 10, and the blade 12, owing to its curvature, causes the earth to be directed toward the share, and this is also assisted by the fender above, which is sufficiently yielding to prevent breakage and to effectually operate on growths in the manner heretofore set forth.

It will be observed that afterarrangement the parts have a fixed position in relation to each other, and an invariable operation thereof ensues as a consequence. This is very beneficial by reason of not requiring continual adjustment or rearrangement during the plowing operation and at all times preserves a regularity in the work accomplished.

Changes in the proportion, dimensions, and minor details of construction could be made without in the least departing from the scope of the invention or sacrificing any of the advantages thereof.

Having thus described the invention, what is claimed as new is-- 1. A plow having a colter at one side of the share, in combination with a seamer secured to the inner side of the colter and consisting of a blade inclined upwardly and rearwardly and curved upwardly between its longitudinal edges, substantially as described.

2. A plow having a colter at one side of the share, in combination with a fender applied to the colter and overhanging the moldboard, and a seamer projecting laterally from the colter and coming between the share and the overhanging portion of .the fender, substantially as described.

S. The combination with a plow having a moldboard and landside, of a share having a vertically-disposed colter at one side adapted to aline with said landside, and a fender secured to the upper part of the colter and pro jecti-ng over the said moldboard.

4. The combination with a plow having a moldboard and landside, of a share having a vertically-disposed colter at one side adapted to aline with said landside, a seamer adjustably mounted on the inner face of the colter above and over a part of the share, and a fender secured to the upper part of the colter and projecting rearwardly over the said mold- .board. 7

5. In combination with a plow, a fender secured at one end to the landside portion of the furrow-opener and arching over the moldboard and inclining rearwardly, substantially as set forth.

6. In a plow the combination with a share provided with a colter, of a fender secured to the colter and arching over the moldboard and inclining rearwardly and terminating in a blunt point, a seamer consisting of a blade upwardly and rearwardly inclined and curved upwardly between its longitudinal edges, and means for adj ustably connecting the seamer to the colter, substantially as and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.
